IMPROVEMENT IN STEAM-GENERATOR.

uitge rlgetnle referrer tu im tigen -litters ttmt mit mating part rftige same;

.Bc it known that I, EDWIN TAYLOR, of Tecumseh, in the county ofLenawee, invented a new and useful Improvement in Steam-Generators; 'andI do 'hereby declare the following to be a full, clear, and exactdescription of th'e same, reference being had to the accompanyingdrawings,which make part of this speci'fication, and in which- A Figure1 is a vertical longitudinal s'ection of a steam-boiler and {ire-boxwith my invention applied.

Figure 2 isa perspective view ot the same. i

Figure 3 is a plan ofthe boiler.

Figure 4 is adctaehed sectional view of the water-reservoir and itsappendages.

Similar letters of reference indicate corresponding parts in the severalfigures.

The subject of this invention is a steam-generatingapparatus in whichthe boiler is completely enclosed within the re-box or furnace, so as tobe entirely exposed to the fire at all parts, and in which the boiler isso suspended and combined with a counterbalance-weight or spring, lthatwhen the latter preponderates, in consequence of thereduced weight oftheboiler caused by the evaporation of its contents, th'e motion therebyimparted to the boiler eilects the opening ofy the valve through whichwater is supplied to the boilerV from an elevated tanl or reservoir.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe it in connection with the accompanying drawings.

A is the dre-box or furnace, and B the boiler enclosed therein.v Theboiler may in likemanner be enclosed within brick-work, when desired. Itwill be seen that the boiler is exposed to the direct action of the fireon all sides as well as at the ends.

By thus arranging the boiler, the most economical and effectiveapplication of the heat is attained.

The boiler B `is held in suspension by means of the chain C, theconnection between the'boiler and the chain being effected by means ofthe hook l)` and plate Dwhich plate connects the inner ends of therods?) b, the outer ends of said rods being clamped, bolted, orotherwise securely made fast'to the boiler, as shown in`ig. 3.

'.lhe chain C is attached to the end of a lever, E, which'is mounted, soas to be capable of vibrating, upon a bridge or support, F, restinguponthe top of the fire-box.

The leverE carries a weight, G, which serves as a counter-balance to theboiler B.

The weight G is hung at any desired point upon the lever E, by means ofits bail,g, and the notches in the edge of the long arm ot' said lever.The notches may represent in inches the amount oi`- water which the`weight G is capable of counterbalancing at its several points ofsuspension. Thus thc weight G, when adjusted ut the extremity ofthe longarm of the lever E, will counterbalance the boiler when charged with amaximum TO ALL WHOM IT MAY GONGERN:

and State of Michigan, have ysupply of water, and to adapt said weighttol counterbalance the boiler with a smaller quantity of water, it isadjusted nearer to the fulcrum of lever E.

"lhe lever E has attached to its end a rod, I-I, whose upper end isattached to a lever, I'l, having a suitable supportingfulcrum upon theelevated reservoir I, (see iig. 4.) The reservoirI may communicate withthe boiler B through the flexible pipeK and a rigid pipo, which latterrises from the boiler and through the lire-box, and is provided with astop-cock, 7c. In thebottom of the reservoir I is a valve, J, which isattached to a tube, J', passing centrally through it, a'nd'projectingabove the water-line in the reservoir. The tube J is connected to thelever H by means of the rod'h.

The smoke-stackor chimney is shown at L, and the steam-pipe of theboiler at M, the latter being provided with suitable guides, the betterto steady and prevent from tilting the boiler B when in motion.

In order tofun understanding of the operation, suppose the-valve J to beclosed, and the boiler, with a full `supply, sustained by the weight Gr.'Nona itis manifest that es the water evaporates, the boiler growslighter,

and' as soon as it becomes incapable of counterbalanoing the weight G',it is raised to a greater or less extent by the latter, and theconsequent vibration of the lever E, and downward motion of the rod H,serve to lift the valve J. A new supply of water is thereby admitted tothe boiler B, which is thus depressed to its former position, inresuming whichthe boiler serves to close the valve J and cut off thewater from the reservoir.

I am aware of no instance inwhich the boiler has been made to actuatethe mechanism/which opens and closes the channel which supplies it withwater.

The tube J', projecting above the water-level in reservoir I, admitssteam above the same, in order to equalize the pressure upon theopposite sides of the valve J, thus preventing the steam lfrom openingthe said valve.

` is the supply-orifice of the reservoir, and z" a cock to try the depthof water therein. When water is being supplied to the reservoir I, thecock k of the feed-pipe K is closed, but at other times it is left open.

It is manifest that a weight attached'to a cord running over a. pulley,or even a spring, or a combination thereof, might be'made to perform thefunction of the parts G E C.

Having described my invention, what I claim as new herein, and desire tosecure by Letters Patent, is-A The arrangement of the suspendedcounterbalanced boiler B within the fire-box or chamber A, and theelevated' tank or reservoir I, substantially as .and for the purpose setforth.

To the above I have signed my name, this tenth day of March, 1868. v I iEDWIN TAYLOR. Witnesses:
